Learning objectives
APPLICAZIONI INDUSTRIALI ELETTRICHE
1) Knowledge and understanding.
This module aims at providing students with basic knowledge and understanding of:
- electric systems behavior in steady state, quasi steady state and dynamic conditions;
- electromechanical system behavior
- electric circuit analysis
- energetic behavior of electric systems
- magnetic circuit behavior under linear assumption
2) Applying knowledge and understanding
Students will be able to:
- analyzing and designing electric circuits
- compensate the reactive power in electric power plants
- make use of analog or digital voltmeter, ampere meter and wattmeter

Assessment methods and criteria
Oral exam. There is a single exam for the two modules making up the
integrated course. As far as Applicazioni industriali Elettriche students will have to demonstrate knowledge of the
techniques for the time analysis and synthesis of electric systems including energy behavior.
It is considered important that student be able to solve simple quantitative exercises by hand calculation.
